Evacuation centers fill up as efforts continue to cool chemical tank

GARDEN GROVE, Calif. (KABC) -- Emergency crews are sending an urgent warning that a chemical leak coming from a large storage tank at a Garden Grove aerospace facility could cause a spill or explosion.

Authorities are calling the toxic chemical leak in Garden Grove a "crisis situation," triggering evacuation orders for roughly 40,000 Orange County residents and school closures.

AIR7 video from overhead on Saturday morning showed unmanned fire hoses and an automatic sprinkler system spraying water on the overheated tank, which is facing a potential catastrophic failure.

The tank at GKN Aerospace contains a highly toxic and flammable chemical used to make plastics. Now, fire crews say the tank is going to fail in one of two ways: either with a spill of thousands of gallons of toxic chemicals or an explosion. Authorities just don't know when or how it will end.

"There are literally two options left remaining," Orange County Fire Authority (OCFA) Division Chief Craig Covey said. "One, the tank fails and spills a total of about 6,000 to 7,000 gallons of very bad chemicals into the parking lot in that area, or two, the tank goes into a thermal runaway and blows up, affecting the tanks that are around them that have fuel or the chemicals in them as well."

Covey stressed that "there is no active gas leak, no plume in the area," but he warned residents to heed the evacuation warnings and remain out of the area due to the possible spill or explosion. Officials said air quality was being actively monitored in the area, and all readings were still within healthy limits.

No injuries have been reported.

It was unclear what initially caused the material in the tank to overheat.

A public information hotline was established at 714-628-7085. Another 24-hour call center is available at 714-741-5444.

Rep. Derek Tran, D-Westminster, issued a statement Friday saying he was "closely monitoring" the situation.

I encourage everyone in the affected area to follow guidance from local authorities and avoid the impacted zones until further guidance is issued."

Temperature in chemical storage tank has increased, not cooled, OCFA says

The temperature inside a damaged chemical storage tank in Garden Grove has been rising by about 1 degree per hour, not cooling or stabilizing as previously believed, an OCFA official said Saturday morning.

Division Chief Craig Covey of the Orange County Fire Authority, the incident commander at the scene, said a drone on Friday had measured the tank's temperature at 77 degrees. However, a subsequent reading of a gauge indicated that the container's internal temperature was 90 degrees.

In a videotaped update posted on social media, Covay said officials are allowing the tank to "cure at a slower rate and reducing its (building) overpressure."

The OCFA is also "bringing people in from all over the country trying to come up with additional options," he added.

"Letting this thing just fail and blow up is unacceptable to us," Covey said.

He added that contingency plans are being employed in case the tank blows up or leaks, and the only people currently at risk are the firefighters and police officers on scene.

Evacuees face uncertainty amid chemical tank crisis: 'We all want to go home'

More than 40,000 people are under evacuation orders as a result of the chemical tank crisis in Garden Grove.

The line of evacuated residents stretched out the door at the shelter set up at Freedom Hall in Fountain Valley.

More than 40,000 people are under evacuation orders as a result of the chemical tank crisis in Garden Grove.

Neighbors joined forces as they searched for hotel rooms after the sudden called to evacuate their Orange County homes due to the danger.

"Got a knock on the door, and I was told we were supposed to leave so I did what I was told," said Jason Reid, who went to one of the shelters.

Neighborhoods across Garden Grove, Stanton and Anaheim suddenly became ghost towns.

After rushing out in the morning, some residents like Diego Espinoza and his mother were allowed to return briefly to grab medication and other vital supplies.

"I feel like the situation has escalated very quickly," Espinoza said. "It was pretty harsh to get out of the house very quickly. We forgot a lot of stuff. That's why we came back here."

While most have heeded the warnings, some are staying behind.

Several shelters have been set up for residents and their pets, with everyone worried about how long they may be out and what could happen to their neighborhoods.

"I think that's the worst part - just waiting and not knowing what's going to happen because we all want to go home," said Jacqueline Reigos, who also had to evacuate.
